While Trunks, 18 and 16 look on, Vegeta reveals his new powers as
an Ascended Super Saiyan. He then proceeds to pummel Cell.
Witnessing Vegeta's new power, 18 begins to question if Vegeta was
holding back in her battle with him several days earlier. 16
assures 18 that Vegeta is not the kind of person to hold back in a
fight, leaving 18 to wonder how Vegeta gained so much power in such
a short amount of time. Afterward, Vegeta reveals to Cell that he
has become Super Vegeta.
